You can use the 
Batch
Post Service Cr. Memos batch job to post several service credit
memos at a time. This can be an advantage if you have a large
number of credit memos that must be posted. You can specify which
credit memos you want to post by filling in the No. field.
It is important to enter all the necessary information on the credit memos before they are batch posted. Otherwise, it is possible that they will not be posted. When the batch job has finished posting, a message shows how many of the service credit memos have been posted (for example, nine out of 10).
To run the batch job, open the Service Credit Memo
window and then click Posting, Post Batch.
You can define which credit memos are included in the batch job by setting a filter on the credit memo number. You can set additional filters on the tab by clicking the Field field, then clicking the AssistButton that appears to the right and selecting the relevant field(s). Fill in the fields as follows:
No.: In the Filter field, you can enter the numbers of the credit memos that you want to post. If you do not fill in the field, all service credit memos will be posted.
Click the up-arrow in the lower left-hand corner of the window to see the result of the filters you have defined for the table.
Posting Date: In this field, you can enter the date that the program will use as the document and/or posting date when you post, if you place a check mark in one or both of the fields below.
If the posting date or document date on a document is blank, the date in this field is used even if you have not entered a check mark in the relevant field.
Replace Posting Date: In this field, you can enter a check mark if you want to replace the posting date of the credit memo with the date entered in the Posting/Document Date field.
Replace Document Date: In this field, you can enter a check mark if you want to replace the document date of the credit memo with the date in the Posting/Document Date field.
Calc. Inv. Discount: In this field, you can enter a check mark if you want the program to calculate the invoice discount amount on the service credit memos before posting.
